The Mono found on the Kino Blu Ray is again a down mix of 5.1.
No it’s not, I actually have the proof that it’s the legitimate domestic theatrical mix, I can share my video if you want
That fool who made that comparison video (and refuses to take it down despite being proven wrong) didn’t realize he actually used the European mix which used the Australian dub but used several sound effects from the American mix (the American mix in addition to changing the dub also added many sound effects that weren’t in the Australian mix), essentially meaning the European mix is a hybrid between the domestic and American tracks
Does this mono mix have the original SFX?
Yes it does, but the “missing” sound effects that comparison video claims were there originally were part of the European mix (and not the original domestic mix) which was a hybrid between the Aussie and American mixes, I had to track down a 1985 Australian broadcast of the movie to prove this
The European track is not included on the 4K release
